Abstract: CONTROL SYSTEM USING TIME DIVISION MULTIPLEXING ABSTRACT A control system for selectively communicating a plurality of sensors with associated remote control devices includes a Master Synchronizer, a transmitter for each sensor and a receiver for each control device. A single signal line is connected to all transmitters and receivers, and a single synchronization line couples the Master Synchronizer to all transmitters and receivers. The Master Synchronizer generates a time frame signal which has a reset portion for resetting all transmitters and receivers synchronously at the start of each frame, and a periodic portion which determines the time slots for each frame and which decrements counters in all transmitters and receivers synchronously. A time division multiplex system is used to communicate each trans-mitter with one or more associated receivers during a pre-determined time slot of a periodic time frame determined by the Master Synchronizer. At the beginning of each frame, all counters are set to a predetermined number representative of the time slot allocated to those units. When their counters are decremented to zero, a time slot is defined for communi-cating a transmitter with its associated receiver or receivers. Thus a transmitter is permitted to send a signal along the signal line which causes a response only in the receiver whose counter has been decremented to zero during the same time slot. A decrementing counter in the Master Synchronizer defines the complete time frame; and when it reaches zero, the transmission of sync pulses to all transmitters and receivers is inhibited for a predetermined time. This absence of sync pulses is used to reset the Master Synchronizer and all transmitters and receivers at the start of each frame. An energy-containing signal, rather than the absence of a signal, is required to activate a control device.

Abstract: ABSTRACT OF THE DISCLOSURE A device for measuring the quantity of raw pasta required to pro-duce the desired amount of cooked pasta.  In the domestic market most packaged spaghetti is ten inches in length and a simple measurer for calculating the required amount of this raw product selected for cooking is a non-stretchable, flexible measuring line that can be looped around a bundle of spaghetti to determine its circumference.  The line is calibrated and can show the number of serving portions of cooked spaghetti that the encircled bundle will pro-duce.  To facilitate its use in the family kitchen the line is provided with a ring on one end thereof that can be slipped over the thumb of the user and holding a bundle of spaghetti, of approximately correct size, in her hand the line is wrapped around the spaghetti to measure its circumference and deter-mine if more or less spaghetti is needed.  To improve the accuracy of the measuring line it is desirable that the calibrations start at a point spaced from the ring and extend therefrom toward the free end of the line.  The re-ference point at which the calibrations begin may be in the nature of an external projection with which the looped line encircling the bundle has sliding engagement and at which point the bundle's circumferential measure-ment is read. A tab on the free end of this line provides a convenient finger grip and its flattened faces may bear useful information, e.g. volume of cooked products that will result from the encircled bundle of raw pasta, cooking time, etc.

Abstract: ABSTRACT OF THE DISCLOSURE A gas burner system for providing a thin, flat flame for use in a long narrow combustion space, has a first air supply plenum  which has a long narrow rectangular cross-section, which is placed above a second plenum or combustion chamber of substantially the same cross-section.  At the junction between the first and second plenum there are longitudinal projections inwardly from both long walls of the second plenum, forming a long narrow rectangular inlet to the second plenum.  A burner assembly comprising an elongated flattened pipe having a plurality of short air baffles welded on each side is supported in this narrow inlet to the second plenum and sub-stantially in the center thereof.  The overall width of the burner assembly is less than that of the inlet so that there are two longitudinal gaps between the burner assembly and the projections for the passage of combustion air.  There are two sets of ports in the lower edge of the flattened pipe. A first set provides downstreamwardly and outwardly projecting ports for the passage of the major gas flow.  A second set of smaller gas ports are drilled substantially laterally to the vertical, and the gas therefrom flows into the surface behind the air baffles where a stable, sheltered flame car be provided, for continuous ignition of the major flow of gas issuing at high velocity from the first set of ports, and turbulently mixing with the air flow downwardly through the gaps.  The walls of the second plenum and pro-jections can be of conventional refractory material, or they can be of metal which is water cooled.

Abstract: COMBINATION EXPULSION FUSE            ABSTRACT OF THE DISCLOSURE          A combination fuse has a current limiting section and a low current expulsion section with the expulsion section within the high current section.        This arrangement makes it possible to increase the length of the expulsion tube as compared to the prior art and provide greater arc cooling without increasing the overall length of the fuse.  In addition the fuse arrangement places one fuse terminal between the ends of the fuse rather than at one end as in the prior art, thereby reducing the strain on the mounting means and the tendency to vibrate.  The expulsion section includes an expulsion tube with a standard fuse link inside.  The expulsion tube is mounted within the casing of the current limiting section to an end closure at one end of the casing.  The expulsion tube projects through an end closure at the other end of the casing.  A connector terminal is mounted to the casing adjacent the end from which the expulsion tube projects.  The current limiting fuse wire extends from the terminal, spirals around the expulsion tube to the other end of the casing and connects there with the fuse link.  The connector terminal also serves as a mounting means.

Abstract: TITLE                  CONTROL SYSTEM FOR AUTOMATICALLY     ACTUATING VEHICLE BRAKES                      ABSTRACT OF THE DISCLOSURE           A motor drives a pump to provide fluid under pressure in a closed hydraulic circuit through a pilot valve to a change speed clutch valve and a directional valve of a multi-speed transmission for an electrically powered vehicle, such as a mine haulage vehicle.  The multi-speed transmission is connected an output shaft to the driven wheels of the vehicle.  A braking force is applied to the driven wheels by a hydraulically operated service brake to effect routine stopping of the vehicle.  Under emergency conditions an emergency brake applies a braking force to the driven wheels by operation of a panic bar positioned in the operator's compartment.  A brake valve connected to the panic bar maintains a preselected fluid pressure in the hydraulic circuit of the emergency brake to retain the brake in a released position.  The hydraulic circuit is interlocked through the pilot valve to the transmission clutch and direction valves.  Depressing the panic bar actuates the brake valve to engage the emergency brake and simultaneously actuate the pilot valve to interrupt fluid flow to the respective valves of the transmission. Transmission of power to the driven wheels is terminated, and the vehicle is stopped.  Actuation of the brake valve also opens the main contactors of the electrical controller that supplies electrical power to the traction motors to stop the motors. A safety brake valve is connected to the hydraulic circuit in series with the brake valve and is operable when the traction motors are stopped routinely or by application of the emergency brake to prevent restarting the traction motors and moving the vehicle until the emergency brake is manually disengaged.
